My dad (80+ Yr old) was diagnosed with cancer at the base of the oesophagus early this year. He received chemo drugs and infusions. He went for his scan and they have found a thickening further up the oesophagus so he will need more treatment, a different type, the injections every other week.
He can eat much better than he did before so we thought it had done a good job of working but is this the cancer spreading? And can the 'new' cancer that has spread not react to the same drugs... Mutating?
I'm just looking for more info as my parents are skimming the surface with their answers.
